# SAW

## Plugin

Plugin module of SAW support is designed to **manage extension packages** that expand the capabilities of the SAW software. In version 8.3, we released the GPU aceleration package, a critical extension designed to significantly boost computational performance, especially for large Stereo-seq chip datasets.

### GPU acceleration package 1.0 (Aug., 2026)

* **Key feature:** accelerates downstream matrix analysis (PCA, UMAP, clustering, etc.)
* **Scope:** applies to the step of secondary analysis, **not to image processing**
* **Requirement**: SAW **8.3.0 or higher** required

{% hint style="info" %}
Before downloading, please verify your server's **CUDA version** (e.g., by running the `nvidia-smi` command) to ensure you select the compatible GPU acceleration package.

By installing the GPU acceleration package, SAW can offload computationally intensive tasks to the GPU, drastically reducing runtime for the following analysis steps:

* Dimensionality reduction: accelerates PCA (Principal Component Analysis) and UMAP (Uniform Manifold Approximation and Projection).
* Clustering: speeds up Leiden clustering.
* Joint analysis: enhances the efficiency of multi-omics/multi-sample integration and batch effect correction (e.g., in `saw aggr`).
